Specification of Letters Patent.

Patented Feb. 23., 1915.

Application filed November 3, 1914. Serial No. 870,019.

To all whom it may concern; .9

Be it known that l, NORMAN DODGE, a citizen of the United States,residing at East Orange, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in TypographicalMachines, of which the following is a specification, reference be ng hadtherein to the accompanying drawlng.

My invention relates to typographical machines, such as linotypemachines of the general organization represented in Letters Patent ofthe United States No. 436,532,

to O. Mergenthaler, wherein circulating matrices are released from amagazine in the order in which their characters are to appear in printand then assembled in line, the composed line transferred to the face ofa mold, the mold filled with molten metal to form a slug or linotypeagainst the matrices which produce the type characters thereon, and thematrices thereafter returned through distributing mechanism to themagazine from which they started.

More particularly, it relates to such machines when equipped with doubleor Janusfaced matrices, that is to say, matrices formed with a pluralityof characters in each of their opposite edges, together with means fordetermining the level of the matrices, matrix-reversing means, andcommon devices for controlling the operation of both said last mentionedmeans.

Machines provided with matrix-reversing means such as those referred toare illustrated in Letters Patent of the United States to Holbourns andLonghurst, No. 951,948, and in the application for Letters Patent of D.S. Kennedy, filed February 21, 1914, Serial No. 820,194.

It is frequently the practice in the use of linotype machines to makelong runs on certain classes of work where two different faces are mixedin the same line, as for example in telephone directories and the like,where the names and addresses are given in a light face type and thenumbers and exchange names in a black face. The specific embodiment ofmy invention permits the shifting of the matrix-reversing meanssimultaneously with the adjustment of the means for determining thelevel of the matrices, this result being secured without specialattention or care; on.the-part of.- theoperator, and without theliability to imperfect results which would arise in the event that theseveral devices were not correspondingly adjusted. The. particular classof work cited is mentioned only by way of example, as obviously myimprovements Wlll be equally applicable in many cases where it isdesired to reverse the matrices and also employ them at diflerentlevels, and particularly where the composite shift is frequentlynecessitated.

In the accompanying drawings, 1 have shown my invention only inpreferred form, but obviously many changes and variations may be madetherein, and in its mode of application, which will still be comprisedwithin its spirit. Similarly it may be applied to other forms oftypographical machines, such as typesetters, typecasters and the like,which handle type or dies, instead of matrices: Generally speaking, Idesire it to be understood that I do not limit myself to any specificform or embodiment, except in so far as such limitations are specifiedin the claims.

Referring to the drawings: Figure l is a perspective view of a portionof a linotype machine with my improvements embodied therein; Fig. 2 is avertical section through the assembler; Figs. 3, 4 and 5 are similarviews showing the parts in different poslitions; and Fig. 6 is aperspective detai As is usual, the matrices X are released by themanipulation of the keyboard R and delivered to the assembler belt S,from which they pass into the assembler T. After the line is composed,the assembler is raised and the line transferred therefrom through theintermediate channel W, from which in turn it passes to the castingdeupon the frame H, and the parts.

. In the present instance ,the reversing device A is slidably mounted inthe frame and is normally forced upward by the spring A so as to bringthe straight or plain channel into operation, but it may be moved in theopposite direction to versing channel into position by the finger key Band the connected link 0. The key B is located in convenient proximityto the keyboard R, and the link 0 is suitably inclined (see dottedlines) and formed to engage the end of the pivoted arm D, the link beingpreferably provided with a roller C to bear upon the nose or outer endof the arm. The arm D passes transversely across the upper portion ofthe reversing device A, and is located above a stud A on the latter, thearm being formed with a plurality of notches D to engage the stud in theseveral operative positions. Normally the spring A holds the device armD, link C, and key B in their uppermost positions, but when the key isactuated, the link 0 depresses the arm and the reversing device so as tobring the channel A into operation, as indicated in Fig. 1. The key Bmay then be engaged with a notch or cut B in the is shown in operativerelation to the. other framework to hold the several elements againstthe tension of parts so far described are or may be of any ordinaryconstruction, such for instance as that presented in the Kennedyapplication,

the spring A The and in themselves constitute no part of my presentinvention, specified.

The assembler T is provided as usual with the two movable blades E andF, whereby the level of the matrices and consequently the selection ofthe characters in their operative edges is determined. The former actsto arrest the matrices in their elevated position and the latter toretain them there, the respective blades being provided with theadjusting levers E and F all in the manner well understood in the art.However, in the present instance I have provided connections whereby thebladesare adjusted by the movement of the previously mentioned key B, sothat when the latter is operated to reverse the matrices. their level insimultaneously controlled. preferably comprise the plate G mounted uponthe vertical rocking frame H, the plate being formed with a notch leverE of the blade E, and with a notch G to engage the lever F of the bladeF, so that when the frame H is tion, the blades will be projected intothe assembler, and when moved in the'opposite direction they will bewithdrawn '-tlierefrom, The plate G is slidably mounted notches G: and

except as hereinafter bring the rifled or reto Fig. 2, it will ment withthe projection J the assembler will be 1 These means G to engage theswung in one direc-.

therein are so formed, that when de'-- 'The connections between theswinging frame H and the reversing key B comprise a pair of verticalarms J and K connected to the frame apd located at opposite sides of itspivotal point, and a sliding piece L mounted on the key which may bemoved thereon to engage either of the two arms and thus swing the framein opposite directionsaccording to its location. The slide L is formedwith two oppositely projecting arms N and O, the former adapted to enterbetween and engage the projections J and 2 on the arm J, and the latterto enter between and engage the projections K and on the arm K, accordinto the position of the slide L. The means or adjusting the slide Lpreferably comprise the finger lever M pivoted to the key B andconnected by the link L to the slide.

In Figs. 2 an its uppermost position with relation to the key B, and thearm N in operative relation to the projections J and J while in Figs. 3and 5 the lever M is shown in its lowermost position, and the arm 0 inoperative relation to the projections K and K. If the lever M be movedto intermediate position (see dotted lines in Fig. 4;), the slide L willbe so positioned as to locate both its arms N and O entirely out ofoperative relation to the arms J and K, in whch circumstances theactuation of the key B effects only the reversal ofthe matrices/andthe'determination of their level will depend upon the manipulation ofthe lever E all in the ordinary manner.

The operation of my improvements will now be clearly understood.Referring first d 4 .the lever M is shown in i be noted that the key Bis in normal position and the arm N in engagej on the arm J whichcondition results in the delivery 0 the retraction character 1 intooperation. If now the'key B be depressed (Fig. 4), the device A isadjusted to reverse the matrices, and due to the action of the arm N onthe projection J the blade E is projected into the assembler, thusbringing the lower character 4 into operation. In other words, theactuation of the key B has effected a change from the upper character onone edge of the matrix to the lower character on the opposite edge.Referring to Fig. 3, the key B is in its uppermost position and the arm0 of the slide L in engagement with the projection K. which condition ofthe parts remeagre suits in the delivery of unreversed matrices, and theprojection of the blade E into the assembler, thus rendering thecharacter 2 operative. If the key B be depressed (Fig. 5), the device Ais shifted so as to reverse the matrices, and due to the action of thearm 0 on the projection K the blade E is withdrawn from the assembler,thus resulting in the delivery of reversed matrices to their lowermostposition in the assembler, and bringing the upper character 3 intoaction. In this instance, the actuation of the key has etfected a changefrom the lower character on one edge of the matrix to the uppercharacter on its opposite edge. If it be desired to operate the parts inthe ordi nary manner, so as to secure any combination of characters,this may be efiected by interrupting the connection between thereversing key and the 'movable' assembler blades, either by adjustingthe slide G or the slide L to inoperative position, as previouslydescribed. As previously stated, I have shown my invention only inpreferred form and by way of example, and as applied toa particular formof mechanism. However, fications and alterations therein, as well as inits mode of adaptation, :will suggest themselves to those skilled-inthe! art, without departure from its scope.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Eat ent of theUnited States, is as follows:
